Army Maj. Jareè Lenore Johnson, Entomology Chief, U.S. Army Medical Research Directorate-Africa, is a board-certified entomologist with the Walter Reed Army Institute of Research (WRAIR). She is currently stationed in Kisumu, Kenya and studies insects and pests in order to monitor their behavior and patterns to prevent diseases among the military population.

What vector-borne projects are you working on?

Insecticide resistance, arthropod vectors and their diseases, insecticidal product/spatial testing, and tracking vertebrate ectoparasites and their associated diseases

What led you to this career?

I was fascinated by critters (animals and insects) at a young age. In college, I started out in animal science because I wanted to be a veterinarian, but fell in love with entomology after accepting a research fellowship to work with ticks/Lyme disease in dogs and humans. Around this time, West Nile Virus entered the East Coast and I had the opportunity to conduct mosquito surveillance for the first time—it was fun! I have two master’s degrees in Animal Health and Diseases and Medical Entomology.

What do you enjoy most about entomology in the U.S. military?

The ability to work with various medically important arthropods and vertebrate pest. The military has given me the opportunity to travel and surround myself with various cultures. There are always new scientific discoveries and I am constantly reading scientific literature to ensure that I am up-to-date on the latest news in medical-veterinary entomology. I am constantly challenged to learn what I don’t know, and that has made me successful in my craft.

Have you contributed to any interesting projects?

I was selected to stand up the Army Public Health Center's first insecticidal resistance program. This grassroots project allowed my soldiers to work on local entomology issues that were not conducted on other installations or Army PM field. This work was rewarding because I was able to teach others and bring a much needed capability to the organization.

Norovirus

Beginning in 2011, the Operational Infectious Diseases (OID) laboratory at the Naval Health Research Center has undertaken routine surveillance of four U.S. military training facilities to systematically track the prevalence of acute gastroenteritis and to establish its etiologies among U.S. military recruits.

Staphylococcus: Staphylococcus aureus is a major cause of skin and soft tissue infection (SSTI). Military personnel in congregate settings (e.g., training, deployment) are at increased risk for S. aureus colonization and SSTI. For a 7-month period in 2016, an observational cohort study of S. aureus colonization and SSTI among U.S. Navy submariners was conducted.

Malaria U.S. Armed Forces, 2017

Infographic
2/14/2018
Since 1999, the Medical Surveillance Monthly Report (MSMR) has published periodic updates on the incidence of malaria among U.S. service members. Malaria infection remains an important health threat to U.S. service members, who are located in endemic areas because of long-term duty assignments, participation in shorter-term contingency operations, or personal travel. This update for 2017 describes the epidemiologic patterns of malaria incidence in active and reserve component service members of the U.S. Armed Forces. Findings • A total of 32 service members were diagnosed with or reported to have malaria, which is the lowest number of cases in any given year during the 10-year surveillance period. • Health records documented the performance of laboratory tests for malaria for 22 of the cases. The tests for 17 of the 22 were positive for malaria ( stick figure graphic visually depicts this information). • In 2017, 75.0% (24 of 32) of malaria cases among U.S. service members were diagnosed during May – October (calendar graphic showing the months visually). • Of the 32 malaria cases in 2017, more than 1/3 of the infections were considered to have been acquired in Africa. Two bar charts display the following information: • Bar chart 1: Numbers of malaria cases by Plasmodium species and calendar year of diagnosis/report, active and reserve components, U.S. Armed Forces, 2008 – 2017 • Bar chart 2: Annual numbers of cases of malaria associated with specific locations of acquisition, active and reserve components, U.S. Armed Forces, 2008 – 2017 The majority of U.S. military members diagnosed with malaria in 2017 were: • Male (96.9%) • Active component (81.3%) • In the Army (75.0%) • In their 20’s (56.3%) Access the full report in the February 2018 MSMR (Vol. 25 No. 2).

Insomnia and motor vehicle accident-related injuries, Active Component, U.S. Armed Forces, 2007 – 2016

Infographic
1/25/2018
Insomnia is the most common sleep disorder in adults and its incidence in the U.S. Armed Forces is increasing. A potential consequence of inadequate sleep is increased risk of motor vehicle accidents (MVAs). MVAs are the leading cause of peacetime deaths and a major cause of non-fatal injuries in the U.S. military members. To examine the relationship between insomnia and motor vehicle accident-related injuries (MVAs) in the U.S. military, this retrospective cohort study compared 2007 – 2016 incidence rates of MVA-related injuries between service members with diagnosed insomnia and service members without a diagnosis of insomnia. After adjustment for multiple covariates, during 2007 – 2016, active component service members with insomnia had more than double the rate of MVA-related injuries, compared to service members without insomnia. Findings: • Line graph shows the annual rates of motor vehicle accident-related injuries, active component service members with and without diagnoses of insomnia, U.S. Armed Forces, 2007 – 2016 • Annual rates of MVA-related injuries were highest in the insomnia cohort in 2007 and 2008, and lowest in 2016 • There were 5,587 cases of MVA-related injuries in the two cohorts during the surveillance period. • Pie chart displays the following data: 1,738 (31.1%) in the unexposed cohort and 3,849 (68.9%) in the insomnia cohort The highest overall crude rates of MVA-related injuries were seen in service members who were: • Less than 25 years old • Junior enlisted rank/grade • Armor/transport occupation • • With a history of mental health diagnosis • With a history of alcohol-related disorders Access the full report in the December 2017 (Vol. 24, No. 12). Go to www.Health.mil/MSMR Image displays a motor vehicle accident.
